Jamaican sprint legend Usain Bolt has backed either Kishane Thompson or Oblique Seville to beat defending champion Noah Lyles in the 100 meters at the world championships in Tokyo.

Bolt is an 11-time world champion, having won consecutive world 100, 200 and 4x100 relay golds from 2009 to 2015 — with the exception of a false start in the 100 in 2011.

The now 39-year-old retired after the 2017 worlds in London, where he won a final bronze in the 100, which was won by American rival Justin Gatlin.
